The Two Fundamental Types of Inertial Navigation Systems 1
The advancements in technology have paved the way for the inertial navigation system to meet all the criteria it’s supposed to achieve.
2
INS has the ability to provide ground plot information, regardless of the flight path, aircraft performance and your position in the globe.
3
Starting from one point, it calculates your present position based on the direction and speed travelled from the starting point.

Earlier versions of the electronic system were bulky and weighing hundreds of pounds, today’s models are so compact and portable that they weigh less than 100 pounds and can fit in a briefcase.

A gimbaling inertial navigation system is typically used on board a missile. It employs three gyroscopes and three accelerometers, with the former establishing a frame of reference of the vehicle’s:
6
Roll Rotation about the axis from the front to the rear of the vehicle
7
Pitch Rotation about the axis from left to right
8
Yaw Rotation about the axis from top to bottom
